hi guys, i,ve got a synthetic carpet to clean on saturday, it has very heavy traffic lanes and is in a 3rd floor apartment, i was going to agitate with my crb but wondered if my rotary with a scrub bonnet would do the job,i intend extracting then finishing with a bonnet to aid drying so if i could use the rotary for agitation it will save me humping my crb up 3 floors ..cheers
